Here ya go just curious if it varies from region to region, esp wondering about our friends overseas but what is considered a word that would basically leave you no alternative but to fight in most situations.

Here (East Coast, USA):
For a guy I would say if someone called you a *****. . That would generally be a "get ready for a fight".

For a girl although I do not know personally but from being around them I would say: **** . They seem to really hate that.

So if you are in New Jersey(prb all East) and feel like a fight there ya go.
I imagine that is pretty much the same accross the country though.
